Patent JP-H08264897-A (JP)
Title: Semiconductor laser
Inventor: OKUDA TETSURO
IPC: H01S5/06
Filed: 1995-03-23
Abstract: PURPOSE: To improve the analogous modulation distortion characteristics of a semiconductor laser and further improve the yield against a distortion standard by setting the element length of the length of a region for forming a diffraction grating to a certain value or less and the amplitude of the hill and dale of the diffraction grating to a specific value or less. CONSTITUTION: Although yield is improved as the formation region length of a diffraction grating 1 becomes shorter, the formation region length of the diffraction grating 1 cannot be controlled easily and the scattering of diffraction grating length due to elements increases. Also, an extremely precise control of As raw material flow is required to manufacture the height of the diffraction grating 1 closer to or less than 200Å and no flat surface can be obtained at the time of burial growth when the diffraction grating is made higher than 260Å. Therefore, the length of a region for forming the diffraction grating 1 set to 1/3 or less of the element length and the amplitude of the hill and dale of the diffraction grating is set to 200-260Å, thus improving the analogous modulation distortion characteristics of a semiconductor laser.

Filed: 1993-03-23
Abstract: PURPOSE:To sufficiently remove noises from a speech signal at all times. CONSTITUTION:In a step S2, the amplitude spectrum of the speech signal is calculated, an advance to a step S3 is made to calculates an estimated value of the amplitude spectrum of a noise from the amplitude spectrum corresponding to a voiceless section, and an advance to a step S4 is made.

Title: High voltage generating circuit of car ignition system
Inventor: IWASAKI SHINICHIROU
IPC: F02P3/02
Filed: 1984-03-30
Abstract: PURPOSE:To produce an optimum ignition current according to an engine condition even if a spark maintaining voltage is changed, by feeding an ignition current, which is rectilineraly increased, to an ignition plug to limit a current amplitude during an ignition maintaining time. CONSTITUTION:When an ignition plug starts to discharge, an inter-electrode voltage is decreased starts to the maintained continuous voltage. The continuous voltage is maintained during a time in which the OFF-period of a MOSFET202 continues. A current flowing through a secondary winding is gradually increased, while the FET202 is staying in an engaging condition. A switch circuit 200 conducts ON-OFF change-over at a high frequency during the specific period of each rotation of an internal combustion engine, and thereby a long-term discharge can be effected within an optimum current range between the electrodes of the ignition plug, irrespective of an engine condition.

Title: Powder ingredient carrying device for vending machine
Inventor: SATO TAKESHI
IPC: G07F13/02
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To solve the inconvenience of the preferential ejection of a replenishment ingredient and the difficulty, etc., of grasping the residual amount of powder in gradients and also to obtain high reliability with a simple structure by fixing a cover which partially covers a route along which the powder ingredients in an ingredient storage container reaches a helical body, to the helical body. SOLUTION: A cover 17 that covers a part of a route along which powder ingredients in an ingredient storage container 14 reaches a helical body 15 is fixed to the body 15 and the cover 17 is formed in a tapered shape in the axial direction of the helical body 15 e.g. in the direction of feeding the powder. Because of this, the supply amount of the powder ingredients to the body 15 is limited in a reverse ejection port side of the body 15 because the route is widely covered by the cover 17. On the other hand, since the range where the cover 17 covers the route becomes smaller gradually as it proceeds toward an ejection port 4 side of the body 15, the feeding amount of the powder ingredients to the body 15 increases.  Therefore, because the feeding amount of the powder ingredients to the body 15 is made equal in the shaft direction of the body 15, it is possible to solve the inconvenience of preferential ejection, etc., of a replenishment ingredient.

Title: Controller for zoom lens
Inventor: KOMATSU NOBUO
IPC: G02B7/08
Filed: 1990-03-15
Abstract: PURPOSE:To hold an image formation position constant at all times by storing beforehand the quantity of the deviation of the displacement quantity of a focusing group from the displacement quantity of a non-focusing movable lens group when the image formation position is held constant as power varying operation is carried on so that the deviation quantity corresponds to the power variation value, and displacing the focusing lens group relatively by the deviation quantity. CONSTITUTION:A zoom position detecting circuit 37 detects the power variation quantity as the displacement quantity of a 3rd lens group as the non-focusing movable lens group. As far an infinitely distant point of material, a ROM 38 is stored previously with the displacement quantity of a 1st lens group and the quantity of deviation from the displacement quantity of the 3rd lens group when a coupling position is held constant as the power varying operation is performed so that they correspond to each other. Further, the microcomputer 31 controls a focusing monitor 18 through a focus driving circuit 36 so that the 1st lens group is displaced by a deviation quantity stored in the ROM 38 corresponding to the detected position of a moving cylinder relatively with the 3rd lens group. Consequently, a shift in the images formation position can accurately be corrected although the structure of a zoom lens barrel is simple.
